Answer:
There are 19.5 extinguishers needed.
Step-by-step explanation:
Given that,
One fire extinguisher be available for every 4,520 square feet in a building.
We need to find the value of x if the number of fire extinguishers needed for a building that has 88,140 square feet.
x = (Area of building)/(Area of one fire extinguisher)
So,
![x=\dfrac{88140}{4520}\\\\x=19.5](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B88140%7D%7B4520%7D%5C%5C%5C%5Cx%3D19.5)
So, there are 19.5 extinguishers needed.
